"Just think for a moment what a prospect that is. A single market without barriers — visible or invisible — giving you direct and unhindered access to the purchasing power of over 300 million [now 500m] of the world's wealthiest and most prosperous people."

"If we left the EU we would end this sterile debate and we would have to recognise that most of our problems are not caused by Brussels, but by chronic British short-termism, inadequate management, sloth, low skills and a culture of easy gratification and under-investment in both human and physical capacity and infrastructure."

"UK businesses are in despair, and with no option but to consider postponing investment, or moving their money and investment from here to the continent. The downsides are becoming more evident as time passes.”

Nick Clegg

"When you win in a democracy you have to take responsibility for delivering the commitment that you made to the British people. May seemed to de-legitimise close on half the voting public. You can't do that in a mature democracy."

"Before the Referendum Britain was the fastest growing economy in the G7. Now it is the slowest."

SirIvan Rogers(Head of the British representation in Brussels - resigned 3rd January 2017)

"Senior ministers, who will decide on our positions, issue by issue, also need from you detailed, unvarnished – even where this is uncomfortable – and nuanced understanding of the views, interests and incentives of the other 27.

"I hope you will continue to challenge ill-founded arguments and muddled thinking and that you will never be afraid to speak the truth to those in power."

John Pienaar (Deputy Political Editor BBC News)

"Then came Brexit … Respect for objective, expert Civil Service didn't last long.

"Civil Servants often keep their worries to themselves.

"A former Mandarin told me: 'Our big worry is if we speak our mind- we won't even be allowed in the room when decisions are taken.' "

Jason Langrish (Negotiator on the Canadian trade deal with the EU)

"Undoing nearly 45 years of integration and shared law will not be a pleasant experience and represents a clear step backwards."

"The Canada deal … will go to some measure on Services, but it simply will not provide that market access that covers agriculture, manufacturing, professional and financial services that the UK is looking for.

"This is a very unconventional negotiation. You are going backwards, not forwards, you are not integrating, you are de-integrating.

"People in the UK will say, ‘That feels like a loss of sovereignty’."

(10th December 2017 at 13.05-15 – BBC Radio 4 "The World this Weekend")

“If you are doing a lot of trade with other places in some ways it is irrelevant whether you are in the EU or not and Germany proves that.

"We keep trotting out this phrase "global Britain". We are diminishing that by removing ourselves from a very helpful trade relationship with 50% of our partners.”

Dr Meredith Crowley, Economist - University of Cambridge:

"UK firms are able to integrate themselves into cross European supply chains, have their manufacturing networks extend across countries.

"Large multinationals co-located their investment and jobs in the UK in order to take advantage of the European market.

"As part of the larger EU trading bloc, the UK was able to extract concessions in negotiating agreements with other countries like China that they might not have been able to extract if they were operating individually."

Miriam Gonzalez Durantez(Legal advisor on trade law, economic relations and the Middle East to both the European Union and the British Government; Lady Clegg)

“No country in history, democracy or dictatorship, ever built success by governing against the interests of young people.”

Michel Barnier

"Without the Customs Union and outside the market, barriers to trade, goods and services are UNAVOIDABLE. The time has come to make a choice."

(5th February 2018, Channel 4 News at 19.00, Visit to No. 10)

“There are extremely serious consequences of leaving the single market and it hasn’t been explained to the British people."

"This affects everybody in the country. Once we know what is on the table, it's not a question of why shouldn't we have a People's Vote. Why wouldn't we? It's pure common sense to go back to the people and say 'This is what we have achieved. Do you want this or do you want something else?'."

(24th March 2018, 8.15, BBC1 Breakfast TV)

Edmund Burke (1729-1797, Statesman and political theorist)

"The only thing necessary for the triumph of evil is for good men to do nothing."

"It sometimes happens that the same Government, the same Party have to execute this volte-face. It may be their duty to do so because it is the sole manner of discharging their responsibilities, or because they are the only combination strong enough to do what is needed in the new circumstance."
